　　Influenced by multiple negative factors, international oil prices have plunged in succession in the past half month. The production of shale oil and gas companies with no financing is unsustainable and will usher in a wave of bankruptcy. The imbalance between supply and demand in the market will accelerate the shift of the focus of the international energy map, from the previous supply-side leading to the demand-side leading, that is, the international crude oil market will be transformed from the seller’s market to the buyer’s market.

　　Influenced by multiple negative factors, international oil prices have plunged in succession in the past half month. On March 18th, the New York Mercantile Exchange light crude oil futures for April delivery closed at $20.37 per barrel, while London Brent crude oil futures for May delivery closed at $24.88 per barrel. Compared with the beginning of this year, the prices of West Texas Intermediate crude oil and Brent crude oil both fell by more than 60%. The sharp drop in international oil prices may reshape the international energy landscape and accelerate the restructuring of the international energy landscape.

　　The imbalance between supply and demand of crude oil has intensified.

　　Nowadays, the basic balance between supply and demand to maintain the trend of international oil prices has been broken.

　　Look at the demand first. The COVID-19 epidemic has spread around the world, and many countries and regions have taken "hard core" measures to prevent and control it. A large number of international flights have been grounded, enterprises have stopped production, and global economic activities have slowed down significantly, which has seriously impacted the global oil demand. Analysts of Lyestad Energy Company lamented that the demand for aviation kerosene, gasoline, shipping oil, petrochemical products and power generation oil plummeted at the same time this year, "this is a rare bleak scene".

　　Bank of America predicts that global oil consumption will shrink to more than 500,000 barrels per day in the first half of this year. If the epidemic situation is not controlled, the shrinking demand may continue into the second half of this year. The head of global commodity research at Goldman Sachs Group pessimistically predicted that oil consumption would drop by 8 million barrels per day. The same view is held by Citibank, which predicts that the global oil demand will decrease by 4 million barrels per day in 2020, a record, and the oil demand in the second quarter will shrink to 11 million barrels per day.

　　Look at the supply. On March 6th, after the OPEC+Ministerial Meeting’s talks on production reduction broke down, Saudi Arabia announced that it would start to increase production substantially, and planned to increase production to 12 million barrels to 12.5 million barrels per day. Russia plans to increase production to 11 million barrels to 11.5 million barrels per day. In order to seize market share, Iraq, Nigeria, United Arab Emirates, Kuwait and other countries have also announced to join the army of increasing production.

　　On the one hand, demand has shrunk dramatically, on the other hand, supply has increased dramatically, the relationship between supply and demand has been completely unbalanced, and international oil prices have been diving. Many institutions predict that if the surplus crude oil cannot find a way out, the oil price may drop below $20 per barrel.

　　The imbalance between supply and demand in the market will accelerate the shift of the focus of the international energy map, from the previous supply-side leading to the demand-side leading, that is, the international crude oil market will be transformed from the seller’s market to the buyer’s market. Faced with sufficient market supply, major oil importing countries have a greater say. In recent years, the new map of global energy has gradually become clear, and the global consumption increase of oil and gas resources mainly comes from Asian countries such as China, Indian, Japanese and Korean. This round of falling oil prices will prompt emerging economies to play an increasingly important role in the global energy market.

　　Shale enterprises will be affected.

　　The international oil price plummeted, and those high-cost oil producers were the first to be injured, and shale oil and gas enterprises, especially those with small scale and high debt ratio, were the first to bear the brunt. It is estimated that at the current oil price, most shale oil wells drilled in the United States will be unprofitable. Elacott, senior vice president of Wood Mackenzie, an energy consulting company, believes that falling oil prices may trigger a new round of deep adjustment in the industry.

　　It is estimated that the production cost of most American oil and gas enterprises is above $50 per barrel. When the oil price drops to $30/barrel, only a few companies, such as ExxonMobil, Chevron and Western Petroleum, can continue to drill new wells to make profits, and the rest will all lose money. Different from traditional oil and gas, shale enterprises must constantly drill new wells to maintain production, which requires constant additional investment. To this end, a large number of shale oil companies have to raise funds by issuing bonds. Nowadays, the sharp drop in international oil prices has affected investors’ expected returns and spending plans, making it difficult for shale companies to raise funds. Small and medium-sized oil companies in the United States have begun to cut their investments, such as Apache, which has cut 37%, and Devon Energy, which has cut 30%.

　　Fitch Ratings, a rating agency, predicts that from 2020 to 2022, American shale oil and gas companies will have debts of nearly $200 billion due soon. Due to the sharp drop in oil prices, their debt ratings are close to "junk bonds", and the financing costs of shale oil and gas companies will rise sharply. The production of shale companies with no financing is unsustainable, and will usher in a wave of bankruptcy and become the first batch of "killed" enterprises. Norway’s Ruizide Consulting Company predicts that the crude oil production capacity of American shale companies facing bankruptcy this year will reach 2 million barrels per day. During the low oil price period from 2014 to 2016, dozens of shale enterprises in the United States went bankrupt.

　　Some analysts believe that the exit of American shale companies is exactly what Russia and Saudi Arabia want. The talks between Saudi Arabia and Russia collapsed at the OPEC+Energy Ministers’ Meeting in Vienna, and they failed to reach an agreement on reducing production and insuring prices, and then they started a price war. The main reason was that American shale companies squeezed their market share. "Kill one thousand enemies and lose eight hundred." By suppressing American companies in the form of price wars, Saudi Arabia and Russia have paid a great price and suffered great losses. Oil revenue of oil-producing countries depends on oil price and output. Now that the oil price is halved, the output must be doubled before the two phases can be even.

　　Besides, oil production in Russia and Saudi Arabia also faces cost constraints. Compared with American shale companies, Russia has a good resource endowment and its oil production cost is relatively low. Developed oilfield infrastructure and efficient railways and pipelines enable Russian oil giants to operate at a lower cost. According to estimates, Russian oil companies can bear the low oil price of $15/barrel. In other words, before the oil price drops to $15 to $20 per barrel, Russian energy companies can continue to maintain production, but their profits have shrunk dramatically.

　　For Saudi Arabia, the cost of oil exploitation is lower, less than $3 per barrel. However, in order to maintain the normal operation of the national economy, other costs attached to oil prices are quite high. Saudi Arabia’s national finance mainly relies on oil revenue to maintain the government’s fiscal balance, so it usually needs a high oil price of $80/barrel to support it. Saudi Arabia’s current account is very sensitive to oil price fluctuations, and it is difficult to withstand long-term price wars.

　　Overall beneficial to economic development

　　The sharp drop in international oil prices is indeed a big plus for China as a whole. As the largest net oil importer, the price of crude oil has fallen sharply, which is conducive to China’s significant reduction in crude oil import expenses.

　　Last year, China imported more than 500 million tons of crude oil, with a daily average of 10 million barrels, an increase of 9.5% over the previous year, and the import expenditure was about 166.3 billion US dollars. Now, falling oil prices will save China a lot of money and increase its current account surplus. Ordinary people have already felt the benefits of low oil prices. Recently, China’s refined oil prices have been lowered into the "5 yuan era", and motorists can fill up a tank of oil with less money. As the blood of modern economy, the decline in energy prices is conducive to reducing transportation costs, stabilizing prices, lowering the high CPI index, and providing more space for China’s macroeconomic regulation and control.

　　On international occasions, the decline in international oil prices is also conducive to China’s expansion of "oil diplomacy" space and provides opportunities for the development of "PetroRMB". Yujun Feng, vice president of the Institute of International Studies of Fudan University, believes that when the international oil market is oversupply and the price is low, China can learn from the experience of the European Union, and modify the clauses in the natural gas trade agreements with Russia, Turkmenistan and Myanmar that are linked to oil prices and pay according to demand, so as to safeguard our interests to the maximum extent. At the moment when "the market is king", major oil and gas producers are eager to compete for China’s market share. China can further increase the diversification of oil and gas imports and urge relevant energy suppliers to provide me with more favorable export prices and other conditions. When the international oil price falls into the era of low price, the "Petrodollar" in the financial market will drop sharply, and the oil transaction will tilt towards the buyer’s market, which is conducive to the internationalization of RMB and provides a rare opportunity for the rise of "PetroRMB".

　　However, the sharp drop in international oil prices will also bring a wave of impact to China’s energy industry. China is also a big oil producer, with an oil output of 190 million tons last year. Low oil prices will make domestic oil fields fall into losses and bring cold winter to local oil producers. Chinese-funded enterprises’ overseas oilfield investment will also be adversely affected.

　　The impact on the new energy industry should not be underestimated. Compared with the oil price of $30/barrel, new energy sources such as solar energy and wind energy will be less competitive in the power generation market, which is directly related to the survival of a large number of new energy enterprises and affects the healthy development of the national new energy industry. The spillover effect of low oil prices will also affect new energy vehicles. A joint study by the University of Chicago and the Massachusetts Institute of Technology shows that before the breakthrough of battery technology, the oil price of $50/barrel will make the development of electric vehicles difficult. Today’s oil price of less than $30/barrel will undoubtedly affect the development of new energy vehicles.

　　Original title:Angry: The "Tricky" in weight loss coffee, online celebrity … …

　　I thought I could lose weight while lying down after drinking weight loss coffee, but I didn’t expect that while enjoying "losing weight", symptoms such as dizziness, nausea and insomnia also followed.

　　This is not a normal reaction to losing weight, but becauseCoffee is added with a prescription drug — — Sibutramine.

　　A few days ago, a typical case jointly issued by the Supreme People’s Procuratorate, General Administration of Market Supervision and National Medical Products Administration revealed that Han Moumou and Hong Moumou mixed sibutramine banned by the state into weight loss coffee and sold it on the Internet on a large scale, with a sales amount of more than 8 million yuan, which endangered the physical and mental health of many consumers.

　　 The cost is 298 yuan in 8 yuan and banned drugs in weight loss coffee.

　　In January, 2019, Shanghai Yangpu Public Security Bureau received a report from a biological products company that someone used the company’s name to produce and sell the so-called "slimming coffee for the world" for illegal profit. The police investigation found that the packaging of this "slimming coffee" looks quite formal — — On the pink box, "production license number" and "hygiene license number" are all available.

　　However, after investigation and verification by the police, not only did the reporting company never produce this "slimming coffee", but these so-called formal licenses and approval numbers were also forged. The identification results show that the product contains sibutramine which is prohibited by the state.

　　Sibutramine is a central nervous system inhibitor, which has the functions of excitement and food inhibition. This drug must be taken in strict accordance with the doctor’s advice and the dosage should be controlled. Once abused, it will lead to insomnia, constipation, elevated blood pressure, dyspnea, gastroenteritis and other symptoms.

　　This harmful "slimming coffee" is favored by consumers who don’t know the truth.

　　During the investigation, the police found that there are many "micro-shops" selling this "slimming coffee" in the online social platform, involving many places in the country.

　　Following the clue of "micro-store", the task force quickly found Mao, the main "consignor" of this product in Shanghai, and mastered its warehouse in Pudong New Area.

　　After combing and analyzing the source of goods and the inflow and outflow of funds of Mao and other "micro-shops", the police found that the final suppliers in the upstream were Han Moumou and his wife Hong Moumou in Shangqiu City, Henan Province.

　　On the one hand, the investigator pretended to be a buyer to make contact with the couple on the online platform, on the other hand, he conducted an investigation around his activity track in Shangqiu.

　　After several days of tracking, it was found that Han and his wife often went to a three-story building in a suburb of Shangqiu.

　　This building looks unremarkable, but there has been a "buzzing" sound of machine mixing and processing in the building. In addition, freight vehicles come every two or three days to transport boxes of goods to express transfer points several kilometers away.

　　Shanghai Yangpu police quickly confirmed that the transshipment goods were the "slimming coffee" involved.

　　In late March 2019, the task force assembled police forces to attack in multiple ways, and carried out simultaneous network-closing operations in Zhengzhou City, Shangqiu City, Zhoukou City, Henan Province and Pudong New Area in Shanghai, and arrested 9 suspects including Han Moumou and Hong Moumou in one fell swoop.

　　The police found equipment for making "slimming coffee" in the apartment building rented by the suspect.

　　The police found equipment for making "slimming coffee" in the apartment building rented by the suspect.

　　The "slimming coffee" found by the police in the warehouse has been packed into finished products.

　　The police seized more than 5,100 boxes and 120,000 bags of weight loss coffee, about 165 kilograms of pharmaceutical raw materials (sibutramine powder) and 4 sets of production equipment, involving more than 50 million yuan.

　　Weight loss coffee, which costs only a box of 8 yuan, was sold to consumers at a price of 298 yuan.From 2018 to the incident, the gang has sold more than one million pieces of weight loss coffee containing sibutramine.

　　In the end, the Shanghai Railway Transport Court convicted Han Moumou and Hong Moumou of producing and selling toxic and harmful food, sentenced Han Moumou to 15 years in prison, deprived of political rights for three years and fined 10 million yuan; He was sentenced to 12 years in prison, deprived of political rights for one year and fined 7 million yuan.

　　The situation of food safety crimes is complicated and severe.

　　With the continuous strengthening of governance in recent years, China’s food safety situation has continued to improve, but its criminal situation is still complex and grim, and it presents new situations and new features such as the interweaving of old and new problems, the interweaving of online and offline, the interweaving of domestic and overseas, and the interweaving of various criminal methods.

　　— — Change "cheese smoked sausage" to "birthday"Some lawless elements disregard the personal safety of consumers, tamper with the production date at will and seek illegal benefits.

　　Shanghai Heyi Food Co., Ltd. deliberately falsified the production date of overstocked products such as "cheese smoked sausage" and expired products, and sold them to the outside world. After being seized, the market supervision department revoked the food production license of the enterprise, confiscated the illegally produced products, tools and equipment, and imposed a fine of 3.01 million yuan.

　　Market supervision and law enforcement officers fixed evidence in the packaging workshop.

　　— — Homemade roast duck is "next to famous brands".In a case of counterfeiting Quanjude, six defendants, including Tan Moumou, purchased a large number of packaging materials marked with the registered trademark of Quanjude from Lin Moumou and others, and purchased vacuum packaging machines, burritos, sauces, vacuum-packed roast ducks, etc., without obtaining the entrustment or authorization of Quanjude Company, and processed and manufactured the roast ducks with counterfeit registered trademarks of Quanjude by assembly, and sold them at low prices.

　　In September 2019, the management of Quanjude Company had a discussion with the procuratorate.

　　 — — The takeaway platform is not responsible.In June, 2020, when Jinan Market Supervision Administration of Shandong Province monitored the third-party platform of online ordering through the Internet and big data and grabbed abnormal data, it was found that two online catering households on the "Hungry" ordering platform were suspected of illegal activities such as not obtaining food business license and not publicizing relevant information. After investigation, Jinan Branch of Shanghai ladas Information Technology Co., Ltd. failed to strictly perform its platform responsibilities and violated the food safety law and other relevant laws and regulations, and was fined 230,000 yuan.

　　Market supervision and law enforcement personnel check in the warehouse of the operating enterprise.

　　Data show that from September 2019 to December 2020, the national market supervision departments investigated and handled 284,800 cases involving food safety violations, and the drug supervision departments investigated and handled 107,700 cases involving drugs, cosmetics and medical devices. The procuratorial organs approved the arrest of 3,945 cases involving 7,298 people and prosecuted 8,791 cases involving 17,066 people.

　　The responsible persons of the Supreme Inspection, General Administration of Market Supervision, National Medical Products Administration and other departments said that it is necessary to further implement the most stringent standards, the strictest supervision, the most severe punishment and the most serious accountability requirements, focus on issues such as "three no foods", "expired foods" and "foods that have not been inspected and quarantined", severely crack down on illegal crimes of manufacturing and selling fake and shoddy foods, and effectively protect people’s health.

　　Food safety is as great as the sky. Crimes endangering food and drug safety infringe on the life and health of unspecified public, challenge the legal and basic moral bottom line, and affect the nerves of the whole society.

　　For such cases, the relevant departments should promptly discover and study all kinds of new situations and new problems, and promptly crack down on illegal and criminal acts of manufacturing and selling fake and inferior food with fancy renovation. The whole society should form a joint force to resist fake and inferior food, and build an effective mechanism for timely detection, investigation and punishment, so that fake and inferior food has nowhere to hide. Consumers should also enhance their awareness of protecting their rights and interests according to law, keep their eyes open, enhance their judgment and take the initiative to resist fake and inferior food.

I spent my childhood in war.

My father, Li Lurong, was born in Nanhai, Guangdong, and worked as a clerk in the administrative organs. Later, he joined relatives as a clerk in Shanghai. My grandfather was a former Qing Dynasty juren with a rich family. My mother, Zhang Ruiwen, inherited her grandfather’s wisdom. She went to school and worked as a primary school teacher. She is thoughtful and opinionated. When her father is away for many years, the whole family is fully supported by her mother.

In 1936, I was born in my grandmother’s home-Dongguan County. I was the first child in my family, and soon I had a second one-my younger brother. I spent my childhood in war. I went to the third grade in Dongguan Yuanyong Primary School and moved to Guangzhou with my family to continue my primary school and junior high school. By the second day of junior high school, I was admitted to Guangya Middle School, which is a school that children from poor families hope to enter. From the second day of junior high school, I entered this boarding school until I graduated from high school, and experienced the liberation of Guangzhou (1950). After liberation, due to the financial difficulties of my family, I insisted on studying with the support of national grants.

Li Yanda as a teenager.

Second, unforgettable and elegant

Guangya Middle School, formerly known as Guangya Academy, was founded in 1888 by Zhang Zhidong, Governor of Guangdong and Guangxi Provinces. Its name is taken from "Broad people are great" and "elegant people are just", which means to cultivate knowledgeable and upright people. In Guangya Middle School, I learned to live independently, manage myself, develop freely and happily, and cultivate my good self-study habit and self-improvement spirit.

I am most interested in physics class.

I am curious by nature and like to explore the unknown. In Guangya Middle School, the course I am most interested in is physics. Mr. Wu Weitang, a physics teacher, gave a logical and fascinating lecture, which showed us a brand-new world. It is a great pleasure for me to borrow extracurricular books, especially reference books on physics. As a result, after a period of time, I couldn’t find any physics extracurricular books that I could continue to borrow in the middle school library. Reading extracurricular books makes me learn actively and deeply.

My diary recorded an impressive physics class. In that class, Mr. Wu asked questions for everyone to answer. "Now ask the fourth question, please answer it. What is the internal current of the battery? Ask Li Yanda to talk about it. " I have thought about this question for a while, and briefly organized what I want to say a few seconds before I stood up. I replied: "Charged ions are attracted by the electric field caused by the two poles and move regularly. Negative ions move to the positive electrode and positive ions move to the negative electrode to form the current in the battery." Teacher Wu kept nodding his head in agreement: "What he said is completely right, and his answer is very good and perfect. Let me ask another question, how to expand the meaning of the current in the conductor and combine the composition of the current inside the battery to summarize the meaning of the current? " Looking forward to everyone. I have been thinking about it for a long time, and finally I think that both electrons and ions are tiny particles with mass, which can be represented by particles. At this time, the teacher’s eyes looked at me and said, "Can you ask Li Yanda to answer this question again?" I stood up and answered briefly, "charged particles are attracted by the electric field and move regularly to form an electric current." Teacher Wu immediately nodded and said, "The answer is absolutely right and can be summarized. Have you thought that electrons are particles like ions? This answer is very good, very rare. Li Yanda must have read a lot of reference books beforehand, and he has a thorough understanding of this question. In the two years since I taught physics in senior high school, no one has given such a complete and comprehensive answer, which is rare. You all study hard at physics,But the power of generalization is not enough, so we should learn from Li Yanda, who summed it up very well. You should know that his answer this time is absolutely right. "Such a compliment is extremely rare for Mr. Wu. Extra-curricular books are really helpful to me. I have read some questions about solution current in extra-curricular books, and I have thought that ions may move. In physics class, the teacher mentioned that "in metal, current only moves electrons, and ions are stationary, but this is not the case in other objects." These words may sound like nothing to other students, but they touched my thoughts and confirmed my understanding. I answered the questions and answers in this class by combining reading extra-curricular books with my experience in class, because these questions would not be talked about in high school physics class at that time.

The habit of reading extracurricular books has benefited me a lot.

I read a wide range of extracurricular books, not only in physics. For example, I have read "A Brief History of Lenin’s Life and Career" and "Marina’s Life Path" and made notes. I wrote in my diary: "This book is so good that it gives me great enlightenment. I like reading books very much at this time. People simply can’t lack books. I especially like reading books about the growth of heroes, typical books about lofty morality, and I like those heroes. A person’s beauty lies not only in his appearance, but also in his heart and whether his character is noble or not. Marina’s goodness lies in her constant upward trend, loyal personality and brave and determined spirit. "

Every time I read a good book, I discuss the topic of life with my partners. Good books are so important to me that I sighed in my diary: "I can’t live without books for a day. The library is the most fascinating place. This feeling has been deeply felt as early as my freshman year." I love what Marx said: I would like to be a bookworm.

From now on, loving reading and reading all kinds of books has become my lifelong hobby, which has also helped me form a self-learning ability. In the first year of high school, I was hospitalized for nearly a month because of illness, and all the courses I missed were made up by myself. Especially when I was studying geometry, I read a book "One Hundred Ways to Solve Geometry Problems" in the hospital, and I actually kept up with the progress. I always feel that I don’t have enough time because I am interested in reading books. Although I also made a reading plan, I never finished it. In addition, as a monitor, I am busy with many things. Gradually, I am used to arranging my time effectively. I often pay attention to the main points and improve efficiency when doing things and reading books. This method is very effective when used in course study. After a class, I can often sort it out with a page, and it is easy to review. Therefore, even during reviewing for exams, I still find time to read extra-curricular books. This habit benefited me a lot in my later study and work.

Third, study in Tsinghua

In college, I have developed a unique set of skills of listening to lectures and reviewing.

After graduating from high school, I was admitted to the Department of Electrical Engineering in Tsinghua University.

I didn’t know Tsinghua University at first, and my first impressions were two: First, Tsinghua is a good place for diligent study, especially the library in Tsinghua University, which greatly meets my demand for books; Second, Tsinghua University’s teachers are very good, such as Mr. Zhong Shimo, Mr. Zhao Fangxiong, Mr. Tong Shibai, etc. They not only speak well in class, but also have outstanding personality charm.

In this demanding environment of Tsinghua University, I have not only laid a solid foundation in basic knowledge, but also developed my thinking method and learning method. Because of the great freedom and difficulty of studying in college, I have developed a unique set of skills of listening to lectures and reviewing in order to adapt to the tense college life. Because I am good at grasping the main points, once I grasp the main points in class, it is easy to understand; In the classroom, I often feel that there are many tedious and repetitive contents in what the teacher says. Just staring at the teacher will lead to low learning efficiency. It is better to use the time between lectures to compare the teacher’s methods with your own ideas and list your own doubts. In order to grasp the main points of classroom knowledge more quickly, I often take time to read more books and do some preview when reviewing. Five minutes before class, I will recall the preview content and get a general impression of the central content of this class. In this way, I think while listening, analyze while listening, and write down the main points and similarities and differences, which greatly improves the efficiency of listening to lectures. Over time, the classroom is no longer a place to memorize knowledge, but a place for me to do analysis and comparison. Therefore, I can often put forward some of my own views, and I can also integrate the knowledge of extracurricular books into the course content. Throughout one’s life, knowledge is accumulated slowly, and only the knowledge that one is very interested in and carefully thought about will be accumulated in one’s mind. It is not difficult to do this, as long as you have the heart and form a habit, the result will be inevitable.

Dialectics has opened a new window for me

My study habit of reading extracurricular books became an active part in extracurricular activities when I was in college. I remember when I was a sophomore, I took part in extracurricular scientific and technological activities about the essence of electromagnetic field. This is a study of the nature of matter. In some people’s view, the appearance of electromagnetic field makes matter "disappear". In order to discuss this problem, I especially studied dialectics of nature. I like reading Laozi’s Tao Te Ching very much. The dialectical thinking method has opened a new window for me. Without dialectical thinking, it is not only difficult for a person to enter the room in science, but also difficult to suffer setbacks in life. The dialectical thought makes me understand the dialectical relationship between success and failure, and between rise and fall, so that I can face failure calmly and attach importance to learning from it. When it goes well and rises, I often realize the crisis and make arrangements for the next leap. I can often analyze and observe a problem from the big picture and the whole, and look at new technologies and potentials from the perspective of development and change. All these have played an unimaginable role in my future work. Consciously combining dialectics with research work is also one of my most important gains in college.

After graduating from college, I spent seven years in scientific research, groping in practice, learning by doing, and learning what I can’t learn in books. Pay attention to the questions raised by practice, the research results should be applied to practice, understand the gap between book knowledge and practice, etc. These understandings and experiences were learned during this period, and I gradually matured in this way. Exploring the unknown and curiosity is my lifelong interest and pursuit, and it is also an endless driving force for forming a way of thinking.

3 broaden your horizons, climb high and look far.

With the increase of knowledge and the gradual expansion of the fields involved, my knowledge is also growing. I found that many things have similar properties and different fields have internal relations, and my horizons are gradually broadened, and my understanding and understanding of subject boundaries and subject development are also suddenly enlightened, and I gradually have my own insights.

I studied automatic control in college, and engaged in electronics and digital control for more than ten years after graduation. In 1959, I took part in the maintenance and operation of the first machine tool program control computer in China. Although a group of young people in Tsinghua knew little about program-controlled computers at that time, a group of young people who dared to think and do it could design and manufacture program-controlled computers by themselves after a year or two of hard work. This has greatly inspired me to further emancipate my mind and dare to think and do it. Then I led the graduate students to develop the first program-controlled computer of drilling machine in China and put it into production.

In 1978, I passed the exam and became the first group of visiting scholars to the United States, and had the opportunity to study at the Massachusetts Institute of Technology (MIT). For some other reasons, my research direction shifted from electronics to signal processing. Although I have only been at MIT for two years, I have gained a lot. The most important thing is to broaden my horizons, and at the same time, I have entered a new research field and found a new direction.

In January 1979, Deng Xiaoping (second row, fifth from the left) cordially received the first batch of Chinese students studying in the United States in the new era at the China Embassy in the United States. The third row from the left is Academician Li Yanda.

I used to major in electronic circuits, and I worked under Mr. Tong Shibai. Before going abroad, Mr. Tong arranged for me to learn microprocessor, and asked me to open this course when I came back. At that time, going abroad required two people to write letters of recommendation. I found Mr. Chang Yong, who is a master of MIT and a doctor of Harvard. Mr. Chang asked me to learn signal processing and bring back the class. So it is written on the application form: the first volunteer microprocessor, the second volunteer signal processing.

The tutor I originally chose when I went to MIT was Professor Fan Li, who was the director of the MIT microprocessor laboratory. However, it was the first time that New China sent visiting scholars to the United States, and several institutions did not make it clear that they would accept these people, including MIT. It is said that when MIT professors discussed whether to accept these visiting scholars, Mr. Lin Jiaqiao urged them to accept them. However, some Jewish professors who are very influential in MIT raised some difficult questions. For example, they suggested that the basic condition for visiting scholars is to have a doctorate, and none of these Chinese have a doctorate, so they can only come to MIT as students, not as visiting scholars. As a student, you have to pay tuition, which is actually not accepted. Mr. Lin Jiaqiao argued that there was no doctor’s degree in China, and emphasized that the level of these people met the requirements. The two sides were at loggerheads, and finally a Jewish professor named Oppenheimer proposed a compromise: let them come in first and see before deciding. Finally, MIT professors decided to conduct an investigation for one year. If these people are qualified, they will be treated as visiting scholars, and if they are not qualified, they will be treated as students and receive tuition fees. Because it was Professor Oppenheimer who put forward this suggestion, he would set an example to receive a Chinese and then report the assessment results to other professors a year later. He is an expert in signal processing. After reading the application materials of all visiting scholars, he found that only I chose signal processing. Although it was his second choice, he chose me. So when I came to MIT, I was assigned to Professor Oppenheimer.

I was 42 years old that year, the same year as Professor Oppenheimer. The first time we met, I told him: We graduated from university in the same year, but I just went through the Cultural Revolution for ten years, and you studied for a doctor and opened up your own research direction, so the two of us have been separated for more than ten years. At that time, my first task was to learn the course well, and I could continue to offer this course when I returned to China.

It is not easy to study in Professor Oppenheimer’s laboratory. I have never seen the computer system in the laboratory and I don’t know how to operate it. Once I was studying the instruction set and tried the functions of each instruction one by one. The last instruction was: Shut down. As soon as I executed it, I shut down the computer system of the whole laboratory. At that time, the whole laboratory was in an uproar, and some people had opinions and opinions about Chinese. But then one thing changed my situation.

Although I switched to signal processing from Professor Oppenheimer, I still have the task of learning microprocessor. During the summer vacation, Professor Fan Li’s laboratory provided an Intensive Course on microprocessors. For one and a half months, more than 30 senior engineers attended classes. The process of learning this course was very tight and the homework was very heavy. At that time, my English was not good and I didn’t understand it very well. The final exam is to give each of these more than 30 people a chip, and ask everyone to build a circuit by themselves. If they can read the information in the chip and display it, they will pass. I am very familiar with the circuit. I was the first to make it in two or three days and passed the exam, which surprised some people. The tutor of this course is a graduate student, who is in close contact with Professor Oppenheimer’s laboratory, and the news spread. Since then, the attitude of people in Oppenheimer’s group towards me has changed greatly.

After spending half a year in Oppenheimer’s group, I taught myself two or three courses, such as Signal Processing, by reading books and watching videos. Feeling that I should do scientific research, I went to Professor Oppenheimer and said that I would take part in the scientific research work in the group. Professor Oppenheimer was very surprised. He always thought that I would only take courses, so he asked me which research group I wanted to go to. I chose seismic exploration. Professor Oppenheimer said that he would have a look at it first, and gave me a topic, asking me to find information to do the calculation myself. A week later, I handed in the results, and he gave me another doctoral thesis for me to read. After more than a month, I understood the paper and put forward my own suggestions for improvement, which made me enter his research group. Professor Oppenheimer is an expert on how to apply phase spectrum. At that time, I realized that phase spectrum is closely related to wave delay, and the information of stratum structure can be obtained by using wave delay. My work has also given Professor Oppenheimer a new experience. It turns out that the phase function he proposed can also be used in the study of wave delay and geological structure. Professor Oppenheimer recognized my work, and our group of people also performed well in their respective fields. Therefore, we were all treated as visiting scholars without paying tuition fees, and later MIT accepted new visiting scholars.

Before going abroad, I was mainly teaching in Tsinghua, and my research was mainly tracking and imitating. Only at MIT did I understand how to do scientific research-make new things! During the two years at MIT, my research shifted from electronic circuit to signal processing, which opened up a new research direction and also learned to consider problems from a higher level. Whether it is electronic circuit, signal processing or feedback control, it is actually a problem of information transmission and processing. From a higher level, they are interlinked. I later studied the Internet from the perspective of information control to solve the congestion problem. The essence of bioinformatics is to study the inheritance of DNA information, and information inheritance determines material inheritance. The essence of life is also an information process. All my later work was carried out along such a line.

MIT’s two-year visit has greatly broadened my horizons, made me see the rapid development of foreign science and technology and our backwardness, and strengthened my confidence in emancipating my mind and daring to think and do. However, the most important harvest is: I stand at a different height and have the feeling of climbing high and looking far.

Five, after returning to China to explore a new way of seismic exploration data processing technology.

After returning to China, I devoted myself to using new signal processing methods to find oil and natural gas for the country, that is, data processing for oil and gas exploration. It is very complicated and difficult to process a large number of oil and gas exploration data by computer to find oil layers buried thousands of meters underground. There are several ways to find oil and gas now, mainly by the so-called "seismic exploration" method. Geologists usually analyze the conditions of oil generation and accumulation in areas based on geological surveys, and then generate seismic waves through artificial explosions in areas where oil generation and storage are possible. The seismic wave propagates downward to several thousand meters of oil layer and then reflects to the ground, and the reflected wave can be received by installing a geophone on the ground, and then the cross section of the underground structure can be obtained by computer processing. Geological engineers analyze these structures, find structures that can store oil according to experience or known knowledge, and finally confirm them by drilling wells. However, in the early stage of exploration, the success rate of well drilling is often very low. Our task is to assist geological engineers to better judge oil layers and improve the hit rate of well drilling. Processing exploration data by computer developed greatly in 1960s and 1970s, and achieved great success. By the 1980 s, this method had become more and more complicated, and the results achieved were getting smaller and smaller.

After a period of research, although we made great efforts, the results were not very satisfactory, and I began to rethink the route of our work. My thinking is not limited to the specific topic at present, but the whole exploration method. I think the well location determined by seismic exploration often fails to produce oil. What is the fundamental reason? My conclusion is that the main reason is not that the computer processing is not fine enough, but that the data obtained by seismic exploration is not enough to determine the location of underground oil layers. From the point of view of information theory, it is a problem of insufficient information. For this problem, no matter how to study the computer processing method, it can’t be solved. The basic way to solve this problem is to increase the amount of information, that is to say, to supplement new knowledge about underground oil layers from other aspects. The more such knowledge is supplemented, the more effective it is to solve the problem. When I look around the whole process of exploration, I find that there are several important ways to understand the underground oil layer: one is that drilling wells and logging provide local detailed information of the underground; The other is the inference and analysis of underground oil layers by geological engineers according to geological conditions. Then, isn’t it just to solve the problem of insufficient information by incorporating logging data and information provided by geological engineers’ experience into seismic exploration data? However, because geology, logging and seismic exploration technology are all very complex disciplines or technologies, and they are self-contained, usually an engineer only knows one of them, and the separation of disciplines has caused the separation of the three to a certain extent. Secondly,There are also great differences among them in technology. The knowledge of geological engineers is vague and it is difficult to describe them accurately and quantitatively. The resolution of logging data is very high, but it is only a "one-hole view" with a narrow spatial scope; Seismic data has a wide range in space, but its resolution is low in local depth. More importantly, the amount of seismic data is huge, which needs to be processed by a large computer. The processing process is complex and it is difficult for manual intervention. It is very difficult to combine other data on a large computer. Therefore, when I realized that if we can combine the knowledge of logging and geological engineers with seismic data, it is possible to achieve new results, I began to consider how to realize this scheme. However, when I asked some experts to integrate the three, most of them shook their heads and said it was difficult. It is not easy to realize the integration of the three under the environment and limitation of large computers.

In the mid-1980s, when Professor Chang Yong came back from a visit abroad, he told me excitedly that a new type of computer-workstation appeared abroad. Its performance is equivalent to that of medium-sized and large-sized computers, but it is small in size and easy for manual operation and human-computer interaction. I immediately realized that a rare opportunity came-it must be possible to realize the combination of the three on the workstation. I have a premonition that the traditional seismic exploration data processing technology is coming to an end, and it is necessary to make bold decisions and embark on a new road. This is the combination of the above three. This analysis has strengthened my determination to overcome all difficulties and embark on a new path. After several years of hard work, my graduate students and I have opened up a new road, and initially realized the combination of the three, and the effect is obvious. Three new high-yield wells have been drilled in Shengli Oilfield by this new method. At the same time, the international community is developing in this direction. At present, it has become a common working mode and an important means of oil and gas exploration to process seismic exploration, geological engineer interpretation and logging data at the same time on the workstation, and to interact or combine them with each other.

Six, some experiences of scientific research work

1 don’t do what others have done.

When I was doing research work at MIT, I had the opportunity to get in touch with Professor Lin Jiaqiao, a famous scholar. He is a scholar I admire very much and his contribution to mathematics is universally recognized. I asked him what he should pay attention to in learning and what suggestions he had for my future research. He told me, "Don’t do what others have done." This sentence is very enlightening to me. I understand what he said, but it doesn’t mean that you shouldn’t do what others have done. If you want to learn and understand a lot of work, you must repeat what others have done. It goes without saying that a lot of development and production work is done on the basis of others’ work. I think the original intention of his words is: the research topic and research goal you have determined should be unprecedented and truly exploratory and pioneering. If we only repeat and make some repairs on the basis of what others have done, it is of little significance in research and will only waste a lot of energy, which should not be valued by a scientific researcher.

At the beginning of my scientific research work, I only took part in existing projects or worked with teachers, but I didn’t seriously consider this problem. When I came back from the United States in the early 1980s, my horizons and the height of seeing problems were different. Professor Lin Jiaqiao’s instruction can be said to hit the nail on the head, which has raised my research work to a new level. It is from the basic point that "no one has done it" that I set my research objectives and methods. Compared with the past, they all went all out, but the results were very different, which really benefited a lot.

Grasp the key and go all out.

I also adopt the methods used in my study when dealing with research work. When the research topic is determined, I am used to grasping the main points and key points, simplifying the problem into one or two key problems, and then going all out to concentrate on solving it. Because the problem is concentrated into one or two key problems, all your energy can be focused on one or two points, forming great penetration like an awl. For example, when I was studying signal processing methods at MIT, my professor was a famous scholar in the field of signal processing, and his research work reached the most advanced level in the world at that time. As my foundation is weak, he hopes that I can take more courses and learn more about the work done by his doctoral students. But I think "nothing ventured, nothing gained". I should not only learn advanced theories and existing achievements, but also be able to apply and even develop them and create something. This is my goal. According to my analysis, the instructor has made new innovations in signal reconstruction, and the most important point is to reconstruct the signal by using the phase function. I will seize this point and study it in depth; On the other hand, I choose oil and gas exploration data processing as an application field, and a key problem to be solved in this application field is the delay of finding the arrival time of signals. I vaguely feel that there is some connection between the two. After repeated thinking, I find that the arrival time of the signal is determined by the phase function, so the phase function can be used to determine the delay time in essence. I was very excited to find this internal relationship, and then I repeatedly thought about how to express the relationship between the two in mathematics, starting with the establishment of the model.To write general expressions. After continuous thinking, I finally found a new method and a new expression to estimate the delay problem by reconstructing the signal with phase function, and proved the feasibility of this new method with simulation data. This achievement made the guidance professor very happy, and personally took me to the relevant research center to report this achievement and write it into his summary report. Later, this achievement was also published in internationally renowned journals. Grasping the key and going all out, this method not only benefits me greatly in my study, but also is the most important weapon in my research work.

Put forward new goals in time, not afraid of failure.

A discipline has its process of occurrence, development and decline, and a person engaged in research in a certain field has to go through a similar process. When a person reaches the peak of his success, it also means that he may go downhill. At this time, he should be alert, have a sense of crisis, and set new goals for himself in time. In addition, I think, if you want to explore, don’t be afraid of failure. My first success is often based on dozens of failures. I am not afraid to admit defeat. When I put forward some new ideas, I am often ridiculed, opposed and sometimes even sharply criticized by some people. I don’t care about any of this, I just laugh it off. I think this is one of my great advantages.

Why am I always exploring? I think on the one hand, it is out of curiosity, and on the other hand, I see greater opportunities. Since I returned to China in 1981, I have been mainly engaged in seismic exploration data processing for more than ten years. My team has made some achievements after many twists and turns in its research work since childhood. Since 1993, when my research achievements were rewarded and I was undertaking larger projects, I felt that my work in this field for more than ten years had developed from the beginning to a peak and was going downhill. I have a sense of crisis, and I think it’s time to set new goals for myself. My feeling tells me that network information is a rapidly developing new field with a lot of opportunities. Therefore, I set out to set up a network information research group to apply the intelligent information processing methods we have studied for many years to network control and network information retrieval. Although we are beginners in network information, we have accumulated many years of knowledge in intelligent information processing and intelligent control. The establishment of this research group has given us new goals and inspired our new research ideas. With the development of the Internet in the world and the information superhighway in China, our new network information research group has also developed rapidly, attracting a group of promising young people, and our research has also achieved rapid results and published papers in important publications at home and abroad. Since 1996, with the implementation of the human genome project, a large number of genetic information and data have emerged, which urgently need further analysis by information scientists.The research of bioinformatics will be an important topic in the 21st century, and our other bioinformatics research group is also working closely with biologists to conduct new research.

In my opinion, the interdisciplinary and interdisciplinary edge is exactly where we can make great achievements. In the information age, we should not be complacent and arrogant, but be very sensitive, pay great attention to the development of world science and technology, make full use of the information obtained from all over the world through communication and opening up, and keep up with the times.

4. Establish an ideal, scientific and democratic team.

Nowadays, scientific research is always a collective behavior. The combination of experience and insight, acumen and diligence can often be more fully reflected in a group. A promising scholar should also be an organized person. Because I often serve as a monitor and a league branch cadre in middle schools and universities, I have cultivated my ability of unity and organization, and accumulated experience in social work for my future study and work. Teacher Chang Yong placed great expectations on building an ideal, scientific and democratic team, and also did a lot of work, which also had a great impact on me. We bring the spirit of daring to challenge the world-class level to the research group, set high standards, encourage exploration, allow failure, promote democracy and discuss on an equal footing in the research group, and gradually form an atmosphere. Through the efforts of the whole group, we have established a common goal and established national self-confidence and pride. Here, as an organizer, it is most important to have ideals and beliefs, perseverance and disregard for personal gains and losses. Fortunately, I often work in such a group, which is often the source of my innovative ideas and inspiration, and the most sensitive part of my vision and touch. It is great fun to do research and exploration in such a young group.

5 About basic research

A problem that has been puzzling China’s scientific and technological circles is that science and technology and economy are two skins, and the two cannot be well combined. Over the years, we have always emphasized that "tasks should bring disciplines" and "science and technology should serve the economy", and we have taken many measures, but there are not many original achievements in innovation, and there are still "two skins" in the combination of science and technology and economy. If we have found the problem and attached great importance to it, it has not changed obviously for a long time, then it is likely that we have a problem in the guiding ideology of solving the problem.

When the Second World War came to an end in 1944, people were thinking about how to change science and technology from serving war to serving social development in peacetime. At that time, President Roosevelt gave this task to Dr. Bush, director of the American Scientific Research and Development Agency. After in-depth study, Dr. Bush and a group of outstanding experts put forward a report-"Science-endless frontier". This report has a great influence on the scientific research and economic development of the United States in the following decades. During this period, American science and technology have been at the forefront of the world, and the American economy has been constantly innovating and developing rapidly with the support of science and technology. When our country begins to get rid of the strong external pressure and various wars and carry out reform and opening up in a relatively peaceful environment, it is worth studying the experience provided by this report.

The main focus of this report is on the importance of basic research, which points out that basic research will lead to new knowledge. It provides scientific capital, and it creates such a reserve from which the practical application of knowledge must be extracted. New products and new technological processes are not completely mature as soon as they appear. They are based on new principles and new concepts, which are painstakingly developed in the research work in the purest field of science. Today, basic research has become the leader of technological progress, which is more clear than ever. A country that relies on other countries for new basic scientific knowledge will have a slow industrial development and a weak position in world trade competition, no matter how sophisticated its mechanical skills are. The report requires that the government’s funds for basic research must maintain a steady increase trend. Dr. Bush also pointed out that basic research should be given special protection and special guaranteed support. In 1968, when the US Congress authorized the National Science Foundation to support applied research in addition to basic research, Bush’s Committee on Science and Public Welfare warned that there is a tenacious law governing scientific research: under the pressure of demanding immediate results, applied research will inevitably exclude pure scientific research unless well-thought-out policies are formulated to prevent this from happening. The lesson is clear: it is pure scientific research that deserves and needs special protection and special guaranteed support.

The report also pays special attention to personnel training. In the part of "Renewing our scientific talents", President conant is quoted as saying: "-In every aspect of the whole field that can be properly called" science ",the limiting factor is people. The speed of our progress in a certain direction depends on the number of truly first-rate talents engaged in the said work. So in the final analysis, our basic education policy will determine the future of this country. "

As for strengthening industrial research, the report points out that "the simplest and most effective way for the government to strengthen industrial research is to support basic research and develop scientific talents". The report points out that "one of the most important factors affecting a large number of industrial research is the tax law", and the report suggests that the domestic tax law should be revised to eliminate the uncertainty of deduction of research and development funds.

I think it is clear that we can learn something from this report. The frontier of science and its potential benefits are still endless.

Seven, about personnel training

1 Character, knowledge and talent

Talent cultivation and postgraduate education have always been my thoughts. What do students want to learn in school? I once said the following words to the first-year graduate students of automation department:

Comrade Gao Shiqi, an old senior in Tsinghua, wrote the following words when he returned to Tsinghua in his later years:

"tsinghua campus studied for eight years, and welcomed the new year after 60 years of hard work.　

Today’s dedication stems from yesterday’s learning.

The achievements of old people come from little diligence. "　

It seems that only by being good at learning can you be a good graduate student, and only by being good at learning can you constantly strive for self-improvement and progress.

What should I learn during my graduate studies? I think we should learn "character, knowledge and talent" in reading and research.

Among them, the most difficult and useful thing to learn is character, followed by knowledge and talent. In fact, Tsinghua’s greatest influence on people is Tsinghua people’s character. During the summer vacation, many visitors to Tsinghua asked me where the moonlight was on the lotus pond in Tsinghua. Moonlight in the lotus pond shows Tsinghua people’s elegant sentiment, while Mr. Wen Yiduo’s angry behavior shows Tsinghua people’s integrity and backbone. What impressed our generation the most was Mr. Wang Ganchang. When the organization wanted him to participate in the development of an atomic bomb to counter the nuclear threat of the United States, Wang Ganchang’s answer was: "I would like to make my country." This reflects Tsinghua people’s life goals and traditions. Sentiment, righteousness and ideals of life have influenced generations. If you don’t improve your character, you have never read. This is just as the great scholar Cheng Hao said: "Today people can’t read. If you read the Analects of Confucius, you are such people when you don’t read it, but only such people after you read it, that is, you have never read it. " I hope we can improve our character by reading.

Secondly, what I want to say is to improve my knowledge. This includes knowledge and knowledge. In my opinion, knowledge is easy to learn, but knowledge is hard to find. There are different realms of knowledge.

Mr. Yu Youren wrote two poems:

"Let the cranes fly for thousands of hectares, and fish for a bay."

These are two kinds of realms, a crane soaring into the sky, and the eyes are all over the world. And fishing is just in the river bend. Only with such vision can we have such knowledge. Generally speaking, as Professor Huang Ziqing said, science can only ask "How", not "why". The students joked that science can only say "good" but not "bad". But I think science should be able to ask both "How" and "Why".

But if you ask "Why", it is often a bigger question. Its thinking needs vision, knowledge and imagination, and there is often no answer. Because if you ask "Why", you may ask "Tao". I have a saying, "Tao can be Tao, but it is extraordinary." On a smaller scale, if you take problems that others don’t know or can’t solve as your research direction, you need knowledge and imagination.

If reading and research can not only learn knowledge from teachers and classmates, but also increase "knowledge", it will be "trip worthwhile".

The third is talent, that is, the ability to solve practical problems. Be able to communicate with others, be eloquent, be reasonable, respect others, be good at uniting people and so on. Some people do everything smoothly, and some people can’t do anything. This is the performance of ability.

Some people say that as a graduate student, a good paper is everything. However, how do good papers come out? If you really do research, you are actually exploring in unknown areas. The process is like groping for the exit of a house in the dark. You often hit the wall everywhere, but the door may be at your hand, and you just pass by. At that time, you may be very upset or even very disappointed, so I suggest you, if you are strong enough, stick to it. Or, you may think it’s an act of god, go back to the dormitory and sleep. It’s also feasible to change the house and look for it next week. But never fake or copy. According to my experience, 80% of the time, "God" will give you an exit.

Because most of our research can only be regarded as "fishing in a stream", rather than traveling around the world like a crane, it is not difficult to find an exit. However, character, knowledge and talent are not given by "God". Only these three things are the true meaning of being a successful person and the ability to help you find an exit forever. I hope everyone will pay attention.

2 Postgraduate education should really face the future

Why is it that China has always imitated and tracked more, repeated scientific research at a low level, created less independently, developed new frontier disciplines slowly, and had few top-notch talents at a high level, especially those who led the development of a discipline? In my opinion, in addition to being limited by China’s economic development level and insufficient investment, graduate education should also bear part of the responsibility.

Talents in new frontier disciplines should be trained among graduate students, not just those in existing disciplines. Graduate students will be brought to undergraduate education when they are mature, thus promoting the renewal of undergraduate courses.

It is a well-known problem that the subject content of undergraduate education in China is slowly updated and the content is aging. The root cause is that graduate students have not made great efforts to cultivate new talents in frontier disciplines. With the development of new subject areas, new subject leaders will naturally appear, which is handsome. We are top-notch in the field of science and technology, and there are few talented people who have a great influence in one field, which is also related to the inability to sensitively cultivate talents in new disciplines in the future in graduate education.

Everyone knows that there will be a large number of breakthrough topics from interdisciplinary subjects, but in the past, we often lamented the difficulty in the development of interdisciplinary subjects and attributed it to the imperfect management system. In fact, fundamentally speaking, the guiding ideology of postgraduate education does not really face the future. This can be said to be an important issue that affects the quality of postgraduate training and the training of real talents. This is not a question of specific management methods, but a question of ideas. Without advanced ideas, there will naturally be no new talent training mode, which is worthy of our in-depth consideration.

Take bioinformatics as an example to make a concrete analysis. Since the implementation of the Human Genome Project in the 1990s, biology, especially molecular biology, is undergoing a major change, from the biology that only focused on one gene or one protein in the past to the new system biology. By identifying tens of thousands of genes and millions of single nucleic acid polymorphisms, genomics will help reveal the root of the problem and find the best treatment for many genetic diseases. The wave of "genomics" such as genomics, transcriptomics, metabonomics and proteomics is promoting this change. This is a great opportunity to give birth to new frontier disciplines and grow new academic leaders. However, many graduate students in this field can’t adapt to this change. Where is the problem? Professor David R. Brown (Professor of Pharmacology, Neuroscience and Toxicology) of the University of Minnesota in the United States thinks that "part of it is an education problem" because we are training pharmaceutical workers who are aware of the progress of genomics and proteomics? Are we training molecular biologists who will participate in the process of drug discovery? Neither. In this new discipline, molecular biologists and drug workers should not only become information scientists, but also the information among genomics, proteomics, physiology, medicine and biochemistry must be mutually convertible, which is the significance of the discipline of "bioinformatics or In Silico".

People of insight, advanced universities and professors in the United States, Britain and Japan quickly seized this field and trained talents in this new discipline with new teaching contents. The new graduate team also vigorously promoted the development of this field. It has become the consensus of some first-class universities that professors should train a group of new people according to the requirements of the frontier of science and the needs of the future, and corresponding management methods have been developed for many years.

If we just think that this is an interdisciplinary problem, I think it is not enough. Education should really carry out the idea that education should face modernization and the future.

Today, with the rapid development of science and technology, the development of science and technology provides a great opportunity for China’s economic development, and also provides a great opportunity for China’s science and technology to catch up. But why is it that China’s innovation ability has been difficult to improve compared with the world, and it has long lacked real talents and masters? I’m afraid it’s not that our intelligence in Chinese is insufficient. I think part of the problem lies in education, especially postgraduate education.

Tsinghua University celebrated Teachers’ Day in 2015.

Viii. Bioinformatics-Opening up New Fields

Around 1996-1997, the human genome project was in full swing, and a large number of genome data emerged. Being very sensitive to "data", I naturally wouldn’t miss such an opportunity.

The diagnosis and treatment of diseases is moving from reductionism to system theory.

Our diagnosis and treatment of diseases is moving from reductionism to system theory. At present, most of the research on life science still stays in local details. In the future, the study of life science should rise to a holistic and systematic height, because life is a whole. We need to combine micro and macro! The Human Genome Project has brought our analysis of the human body system into the gene level and an unprecedented field. In order to understand the occurrence of diseases, we are eager to understand the function of genes and protein. However, with the exception of a few genes and protein, most genes and protein do not work alone. Most genes and protein often interact with each other, and their relationship is like a very complex network.

We are faced with the following problems: searching for genetic variation that leads to genetic diseases in complex biomolecular networks, searching for drug targets for treating diseases or symptoms from gene protein networks, and then searching for cancer markers.

How to analyze this network? We can’t break up the network and analyze it in multiple parts, but we must analyze it as a whole; However, usually we only know a small part of this complex network. How can we analyze the role of genes or protein from a part of the network? This problem has been bothering us for nearly ten years!

2 Correlation analysis-relationship inference is a breakthrough.

Correlation analysis is a breakthrough! The early breakthrough of this problem lies in finding mutant genes of non-familial genetic diseases. For familial genetic diseases, we can find the corresponding family and find its special gene mutation through linkage analysis; However, for non-familial genetic diseases, traditional methods are no longer applicable. In desperation, people have come up with correlation analysis: simultaneous occurrence is correlation.

Divide patients and healthy people into two groups, and find gene mutations that appear in patients but not in healthy people. These gene mutations are "related" to genetic diseases. Of course, it is not enough to find the related gene mutation, but also to confirm the truly disease-related gene mutation through prior knowledge, mechanism analysis, experimental verification and other methods, preferably through independent verification by a third party. Finally, this method was proved to be feasible, and with the continuous expansion of the experimental population, it was extended to the whole genome analysis and achieved remarkable results.

We further expand the correlation analysis into relationship inference and propose the CIPHER algorithm. We assume that phenotypes are more similar and related genes are closer, that is, "the distribution of phenotypic similarity" is consistent with "the distribution of gene proximity". Given a phenotype, we can find the corresponding genes. The key of this method is to combine the macro and micro, and to connect the characterization with biomolecules. By using the phenotypic correlation, we can find gene mutations with similar phenotypes from known phenotypes, and we can find drug targets for diseases. By using the "relationship inference" method, we have succeeded in some applications.

The change of diagnosis and treatment of diseases from reductionism to system theory is a major development of medical undertakings, which is of great significance to early diagnosis of diseases, precise medical care and drug research and development. Substantial progress has been made in this regard.

3 big data is more about big data.

Relationship inference enables us to understand the meaning of big data more deeply-to provide all aspects of "relationships", which plays a key role in solving complex system problems!

There are a lot of omics data in molecular biology, and there are also a lot of data on diseases and medicine, which is a veritable big data; However, when we search cancer data, we find that the sample size is very small, because even if they are both liver cancers, there are many subtypes, because there are many possible combinations of mutations, and they are closely related, but they are not samples of the same class; What big data gets is actually a high-dimensional small sample, which is "relationship" big data! It is precisely because of the "relationship" provided by big data that relationship inference is of great use. Vigorously developing relationship inference is very important for the prediction and intervention of biological system, social system, social system, financial system, economic system and military system.

Today, science and technology have experienced Newton’s mechanics, Einstein’s theory of relativity and quantum mechanics. It seems that they have developed very richly and profoundly, and mathematics has developed perfectly, with more and more branches of science becoming more and more specialized. When science seems to be omnipotent, when people really face the complex world, they suddenly find that all science and technology are so limited and simple; When people explain the world with the perfect law, they find that they often run into a wall, and the contingency of world development is so great! What the hell is going on here? Now, even the basic problems, people are shaking their faith in the past "truth". For example, how did the universe come into being? Did organisms evolve according to Darwin’s theory of evolution and the principle of survival of the fittest? What is the secret of life? And so on, this is really a wonderful era. In my opinion, the boundaries of various disciplines are becoming more and more blurred, and interdisciplinary subjects have become the fastest-growing disciplines. With the development of computers, the realization of the human genome project, the emergence of global networks and the high-speed exchange of information, the science and technology of human society are developing at an unprecedented speed, and we are facing a new era of science. Random and nonlinear new analytical methods are making great and even fundamental changes in the analytical methods and conclusions of various disciplines in the past. This is a golden age that provides great opportunities for people engaged in scientific exploration! We are living in such a lucky era. In this era, we dare to imagine and be good at cross-research.It is very important to dare to grasp things in essence and in general. Only in this way can we seize the opportunity of this era to the maximum extent and be worthy of this era. I hope such talents will appear more in the East and in China.

When it comes to Liu Yifei, everyone will think of her little dragon girl in "The Condor Hero". The feeling of not eating human fireworks, even Li Ruotong praised her. However, in real life, she is very down-to-earth, and she has adopted many stray cats with love.

It has to be said that Liu Yifei’s debut is zero scandals, and the only boyfriend she admits to is Korean Oba Song Seung-heon. I still remember when they first announced their relationship, the Internet exploded, and countless otaku men cried bitterly.

Surprisingly, just when they were about to talk about marriage and love, they suddenly announced their breakup, but the fans were very happy. After all, everyone felt that only Hu Ge was worthy of the fairy sister, but Liu Yifei didn’t interact with him at all these years, and even her birthday wishes were concise and concise.

In an interview, it turned out that Liu Yifei had liked someone, and he was Lin Zhiying. It is known that they met because of "Dragon Babu", and then there was an affair, because Lin Zhiying had publicly stated that Liu Yifei was very understanding and in line with his girlfriend standards.

It is worth mentioning that Liu Yifei, who has never appeared in a MV, agreed to be the heroine of Lin Zhiying’s new album, just like a couple in love. However, until Lin Zhiying and Chen Ruoyi got married, Liu Yifei did not say it, which is really good luck.

However, no choice is the best choice. The art of life lies in giving up, and giving up is for better possession. This is very similar to Liu Yifei. This also reminds the editor of the story of the "Perfect" solo drama "Miss Mudslide Confession" that fooled the heartbeat boy three times!

It is reported that as a "swimming coach", the girl was once abandoned by her boyfriend because she was too girl, but she knew how to give up. Finally, the girl finally met a boy who could make her heart move. Although she knew that she was not obedient enough, she still took the initiative to attack.

And after the girl’s carefully arranged confession scene, it was very romantic! And the boy was also moved by the girl’s sincerity and bravery. Most importantly, the personality and interests he admired were very similar to him, which could reduce friction in future relationships.

Indeed, the most important thing is that the two of them can be together, and Liu Yifei can’t get together with Lin Zhiying, which may mean that they are not suitable. Besides, as long as you are good enough, there will naturally be better waiting for you.

Having said that, Liu Yifei and Lin Zhiying did not have a perfect ending, but at least they loved each other, and this beauty is still retained in their hearts. So, do you like Liu Yifei? Is she a good match for Hu Ge?

Sun Yang was on fire. Many people may not have known this actor before the release of "All in All Out", but who would have thought that he quickly came out of the circle with the role of Ah Cai in the film, and occupied the hot list of Weibo and other platforms. Many netizens said that "watching anti-fraud movies fell in love with fraudsters".

Why did Sun Yang become so popular? Without a doubt, he made Ah Cai a very three-dimensional character, which left a deep impression on the audience. Ah Cai was a thug of the fraud group, ruthless and ruthless, but he also had another side. When he faced Anna, he showed an innocent side that made many audiences sink into this character.

He would hand over the sanitary napkin when Anna came to his aunt, pick his finger when punishing Anna because he couldn’t bear and felt sorry for her, and finally create the illusion of Anna’s fake death to help her escape. Many people expressed that "all idol dramas were weak in an instant" when he finally undressed and waved goodbye to Anna. Of course, the premise of all this must be that Sun Yang’s appearance is eye-catching. Born in Hong Kong, China, his own Hong Kong-style temperament makes the audience shout "It is my destiny to fall in love with Hong Kong boy".

As Sun Yang became popular, his past was also exposed by netizens. Born in Hong Kong, studied in Taiwan, and was a classmate of Xu Guanghan, both of whom attended China Culture University. After finishing high school, Sun Yang did not expect to go down the road of acting. At that time, he went to a clothing school, worked everywhere, distributed flyers, worked as an errand at a relative’s company, and interned at the trendy store founded by Edison Chen. While in college, Sun Yang joined the school’s drama club, which inspired his interest in acting.

Sun Yang entered the entertainment industry at the age of 25, and his first work "Dadaocheng" starred in a small role. In the years since then, he has also been playing supporting roles and small roles. Of the works he has starred in in these four years, perhaps the most well-known is "Late Night Canteen", in which he plays the "regular" of the late-night canteen, a small staff member, Sun Jian, in the play. The appearance of the middle-parted hair and suit in the play may make it difficult to associate with him in "desperate".

Sun Yang’s first male lead role was in the movie "Over Spring", and it was this movie that made Sun Yang gradually seen. Sun Yang plays a social youth Ah Hao in this film. Maybe Sun Yang’s natural ruffian spirit makes him handy when playing such roles. Whether it is Ah Hao in "Over Spring" or Ah Cai in "All in All," Sun Yang performs very well. The film was also shortlisted for several film festivals such as Berlin and Pingyao, and was well received in the industry. Although it only received 10 million at the box office after its release, Sun Yang’s acting skills have been recognized by the industry. During the selection of the male lead in "Over Spring", the famous director Li Shaohong interviewed him and was deeply impressed by Sun Yang, which also made Sun Yang play the role of Ding Xianrong in the costume drama "Song Dynasty Palace Ci" directed by him.

"All or nothing" will be followed in September by "The Eighth Suspect," another film by Sun Yang, which was filmed four years ago. At the time, Sun Yang was photographed during an audition for the role of Chen Xinnian in the film.

Sun Yang also appeared on the variety show "Actors Please Take Place." Dapeng, who was the founder of "Actors Please Take Place," invited Sun Yang to appear on the show because he and Sun Yang were filming "The Eighth Suspect." In the show, Sun Yang played Cheng Fengtai, Hong Shixian and other roles, and was eliminated in the third stage.

Ah Cai and Anna in "All in All Out" made many viewers drink candy, and this was not the first time Sun Yang and Jin Chen had collaborated. As early as in "Great Girl", the two had collaborated, but their relationship in the play was not a couple, but a relationship between superiors and subordinates. Sun Yang’s official role in the play was Lu Ke, played by Li Yitong, and Shen Siyi, played by Jin Chen, was his best friend, so some audience members joked, "No wonder I let Jin Chen go, it turned out to be my girlfriend’s best friend."

Sun Yang’s fire has also become the flow code of "All in All", as the crew roadshows everywhere, helping "All in All" box office continues to rise, less than half a month of the box office will exceed 2 billion, surpassing the film fault released in the same period First, the total box office is currently ranked fourth in the 2023 film box office list, and in September Sun Yang starred in "The Eighth Suspect" will also be released, in the recent official publicity said that Chen Xinnian, who starred in it, is a "cold madman", let’s look forward to what kind of performance Sun Yang will bring.

1905 movie network feature In the new film released on New Year’s Day, Lin Zhenan, the crazy drug lord, fights fiercely in front of outsiders, but leaves all his tenderness and preference to Vivian.

The "Deser CP" formed by the two was also dubbed "Pure Love War God Combination" by netizens.

In an exclusive interview with the 1905 film network, Liu Yasse talked about his last collaboration with idol Andy Lau, which dates back to the 2015 film. At that time, she was just an inconspicuous supporting actor around Andy Lau.From supporting role to heroine, Liu Yasse’s transformation in the past 8 years is obvious to all.

Just after filming "Stealth", Liu Yasse ushered in one of the most important moments of his life – winning the Best Actress Award at the 40th Hong Kong Film Awards for her role in Wang Tao.

More than a year later, this trophy still had a heavy meaning for Liu Yasse, "It let me know that all the choices I made were right, and it also let me know that I can be seen for my role!"

Liu Yashe was interviewed by 1905 Movie Network

The trophy is a summary of the past and a new starting point for the future. "I will continue to work hard to meet better characters."

Talk about characters

"Vivian is like a grown-up Wang Tao"

Sixteen years later, Andy Lau once again turned his image upside down as the villain, the two-faced drug lord Lin Chun-an. Some audience members joked: "This is the worst and most ruthless character Lau has played in more than 200 roles".

Even such a murderous "demon" has its own "weakness", which is Vivian played by Yasse Liu. The relationship between the two can also be described as unconditional love and trust.

Liu Yasse recalled that when she received the script, what moved her the most was the sentence in the character biography "Except for lovers, they are all outsiders", which made her suddenly find a support point for shaping Vivian, the insecure drug lord’s wife.

This firmness and single-mindedness is also in line with her own view of love to a certain extent, "I think if love is to be single-minded, the only love is the most effective love. At the same time, love must be mutual. If the balance of love is very flat, if one party is tilted, it may be unstable."

In order to make the characters more three-dimensional and full, Liu Yasse did a lot of homework in advance, made up the background of the characters of Vivian and Lin Jinan and experienced various stories together, and internalized them into the details of the performance.

"At first glance, everyone will think that Vivian is a silly and sweet love brain, very well-behaved and gentle, but in fact, there are a few scenes and a few shots that can show that Vivian is not simple."

For example, Vivian has the habit of kneading paper balls when she is nervous, which is a special design by Liu Yasse. "Because the character has experienced pain and is emotionally ill, Lin Jinan will be very uneasy and anxious when he is not around."

Because of this, some fans say that Vivian is very similar to "Wang Tao" (Liu Yasse’s role in "Wisdom Teeth") who grew up in a parallel time and space.

Liu Yasse bluntly said that he had a similar feeling when he first got the script, "If the character Zhan Ge in’Wisdom Teeth ‘hadn’t died, they could have been completely connected. They have all been raped, and it is because of this that Vivian feels that Lin Zhenan who saved her is a ray of light in her dark life."

Talk about cooperation

The second match feels completely different

When it came to "Wisdom Teeth", one had to mention another lead actor. "Stealth" was also the second collaboration between the two. As the relationship in the play changed dramatically, the atmosphere outside the play became much more relaxed and happy.

"When I was filming’Wisdom Teeth ‘, when I saw Brother Jia Dong at the scene, I was always quiet, because I was afraid, I was really afraid." Liu Yasse said, "This time it’s much easier to see Brother Jia Dong. It’s a completely different feeling."

For Liu Yashe, Lin Jiadong has always been a teacher and a friend. In the process of the second collaboration, she will also ask Lin Jiadong for advice if she does not understand the role, which has benefited her a lot.

Not only Lin Jiadong, but also the "second match" with Andy Lau has a special meaning to Yasser Liu. From childhood to adulthood, Andy Lau has always been her idol. When she was a child, in order to compete with her cousin, who could see Andy Lau at first glance and smash his head, leaving scars.

But when she heard the news that "Brother Hua asked her to play his wife", Liu Yasue’s first reaction was nervousness. Later, the boss’s words made her put down the torn, "Do you know how many girls in China will envy you?"

"Yeah, I don’t want to regret it at that time, and I don’t want to be jealous of others!"

Liu Yasse still remembers that 8 years ago, when he first collaborated with Andy Lau in the movie "Lost Orphan", he only dared to hide behind his back and secretly observe and appreciate his idol. It was not until the day of the end that he mustered up the courage to take a photo with Andy Lau, "That was the first time in my life that I asked for a photo."

At that time, Yasser Liu did not expect that he would become the heroine of Andy Lau eight years later, nor did he expect Brother Hua to remember the red-haired girl in "Lost Orphan" after many years.

This respect and warmth from an idol is both pressure and motivation. "Brother Hua gives people a very kind feeling, which makes me put down my nervousness very quickly."

Talk about acting

"Continue to meet better characters"

Many people do not know that Liu Yasse starred in the film directed at the age of 17, and the film also won the Tokyo Film Festival Jury Special Award that year.

At that time, Yasser Liu was sitting in the audience and heard the audience applaud when the curtain ended. It was a wonderful experience, and it also made her feel the charm of the big screen and the value of being an actress for the first time.

On the road to acting in the future, she has played "Li Rexue" in succession, Qiqi in "The Legend of Qingqiu Fox", Su Xi in "Lucky is Me"Volunteer insmallmonth,"Mai Passerby"Single mother Liang Huiyan and other characters in…

In the process of trying, Liu Yasse also felt confused and wanted to give up. But fortunately, every time there is a role that pulls her back to the path of acting.

This time it’s Wang Tao in Wisdom Teeth.

In Liu Yasse’s opinion, he and Wang Tao had a lot in common, and they both had a stubborn "vitality" like a little stubborn who couldn’t be beaten to death.

In order to survive, Wang Tao struggled to survive in the cracks; at that time, Liu Yasse also drifted north for many years, struggling to find the opportunity to gain a foothold in the entertainment industry.

This mutual achievement between actors and characters is so precious that it has finally turned into a heavy Academy Award for Best Actress trophy.

Liu Yasse, who stood on the podium, said: "The film has given me a beam of light. In the future, I hope to accompany the film to go further."

In the interview, recalling the highlight moment more than a year ago, Liu Yasse still expressed great significance to himself.

"It has achieved one of my goals. When I was a child, I said that I must get a queen!"

"It also let me know that all the choices I made were right. The lows I went through and the ridicule I received helped me, and it also let me know that others can see what I have done for my role."

But at the same time, Liu Yasse also knows that the trophy is largely due to the role of "Wang Tao", and that he still has a long way to go as an actor.

"I still need to work hard to meet better characters."

From singer, actor to variety show, Liu Yasse said that he does not want to set limits on his future self. "I hope that the road of life can be more experimentation and different experiences. People live for a lifetime, and they have to do more things in a limited time."

The identities may be diverse, but the dedication in her heart that goes all the way seems to have never changed, just like the words she once wrote:

"I really have stubbornly believed since I was a child that I can reach where I want to go through hard work.

Maybe it takes a little longer, maybe the road will be longer, but every step is closer, and every time is an opportunity. "

　　On June 13th, the State Council issued the Notice on Establishing the Central Adjustment System of the Basic Endowment Insurance Fund for Enterprise Employees, and decided to establish the central adjustment system of the endowment insurance fund, which will be implemented on July 1st, 2018.

　　You Jun, deputy director of the Ministry of Human Resources and Social Security, explained that due to the difference in population dependency ratio and other reasons, the problem of fund imbalance between provinces has become more and more prominent. However, it is difficult to solve this problem by provincial overall planning, so it is necessary to improve the overall planning level and make appropriate adjustments to the fund nationwide.

As the saying goes, "Lantern Festival is held on the fifteenth day of the first month". As another major traditional folk festival after the Spring Festival, the main theme of the Lantern Festival holiday atmosphere is the word "noisy".

Lantern Festival viewing began in the period of Emperor Han Ming in the East. When Emperor Wen was in the Han Dynasty, the government ordered the 15th day of the first month to be officially designated as the Lantern Festival. The Lantern Festival in the Han Dynasty lasted for one day, which became three days in the Tang Dynasty and five days in the Song Dynasty. In the Ming Dynasty, the lights were lit from the eighth day until the night of the seventeenth day of the first lunar month, for ten days. In the Qing dynasty, the festival was shortened to four or five days.

During the Lantern Festival, festivals and customs all over the country are colorful and numerous. Here are 10 famous ones:

First, walk on stilts

Walking on stilts is a very old folk performance, which appeared as early as the Spring and Autumn Period. On the Lantern Festival, this kind of folk activity of walking on stilts is popular in many places. Stilts are usually made of wood. Make a support point in the planed wooden stick to put your feet, and then tie them to your legs with ropes. Performers can not only walk freely on stilts, but also do various difficult movements such as splitting forks, jumping on benches, dancing yangko, dancing knives and making guns.

Second, the lion dance

Lion dance is an excellent folk art in China. During the Lantern Festival or other assembly ceremonies, the folk will entertain by dancing lions. This custom originated in the Three Kingdoms period and was popular in the Northern and Southern Dynasties. It has a history of more than 1000 years.

Third, the flower viewing lamp

The custom of viewing lanterns on the Lantern Festival originated from the period of Emperor Han Ming. During the Yongping period, Emperor Hanming strongly advocated Buddhism and ordered "burning lamps for Buddha" in palaces and temples on the fifteenth night of the first month. Later, the custom of putting lights on Lantern Festival spread to the people in the court. Every time during the Lantern Festival, no matter the gentry or civilians, every household will hang lanterns and the streets will be brightly lit.

Fourth, playing dragon lanterns

Playing dragon lanterns, also known as "dragon dancing", has a history of more than two thousand years. Playing with dragon lanterns originated from people’s worship of dragons.
